Humans – The original computers

Humans and computers are surprisingly similar! As we already know, computers have input devices, CPU’s, long and short term memory as well as output devices. Firstly let’s look at computers: There are many fancy add-ons for computers, but the basic components of the computer are simple and universal. If 1 of these main components is missing, it’s not a computer. The 4 essentials of every computer system are: a motherboard, a Central Processing Unit (CPU), memory, and a hard drive. These components are installed in a case to which are attached a monitor, a keyboard and a mouse. That’s your basic computer.


The motherboard is the foundation. It’s the circuit board where everything is attached to – the CPU, memory, hard drive, monitor, mouse, keyboard, add-on cards, even additional peripherals like printers, scanners, and speakers. The motherboard is like the nervous system and skeleton of the human body – it provides support for the internal components and also passes information between the computer parts.


If the motherboard is the nervous system, then the CPU is the brain. Most of the mathematical manipulations that make computers operate are done by the CPU. Other components may also have their own processors, but their results still have to be passed through the CPU. The speed of the computer is usually measured by the speed of the CPU. Even though other factors also affect overall speed, the CPU rating is generally seen as the single most important measure of performance. Modern CPUs speeds are usually measured in GHz (gigahertz) e.g. 4.0 GHz and 5.0 GHz, although each passing month will see increasing performance. This measurement refers to the number of calculations the processor can make in 1 second. The higher the number, the faster (better) the computer. CPUs generate a lot of heat doing this work, so they need a heat sink and fan to keep them from overheating. Heat is a major enemy of the computer and directly affects its life span.

Computer Memory

RAM chip (Random Access Memory) is the part of the computer that stores information the computer needs while it is operating. It is Random Access because the computer can get the data in any order, not necessarily the order in which it is stored. Generally speaking, the more RAM the better. 2gig to 8gig is common for memory. The most common type of RAM used in many machines is DDR-SDRAM, which stands for double-data-rate synchronous dynamic random access memory. We already know what the RAM part means. DDR means that the data is accessed twice as fast as ordinary RAM. The latest type of RAM is DDR2. It offers even faster access rates and is quickly becoming the standard for computer memory.

Hard Drive

All the data contained in RAM is lost when the computer is turned off, so there has to be a place to store it permanently. This is what the hard disk is for. It holds the computer’s operating system. An operating system like Windows uses around 4 gigabytes of hard drive space. The extra space is used to install computer programs and to store your personal data. 250 gigabyte hard drives are common, but you can get hard drives with much higher storage capacity. Furthermore, you can install more than 1 in a computer case for added security and convenience.


All you need to complete the basic computer system is a monitor, keyboard and mouse. Accessories like a printer or scanner are useful for office work, and gamers will probably want to add speakers and joystick controls. So there you have it. The basic computer needs just 7 major components. For the best performance, these components must integrate well. The motherboard is the most important component for determining the type and specification of the other parts. Choosing an appropriate motherboard for your computer needs is the first step and may require a quick call to your local geek.

Now let’s look at similarities with humans:

-A computer has input devices like keyboard and mouse – Humans have input “devices” like eyes, ears, nose, tongue, skin. All information coming in from the outside world comes through our 5 senses.

-Computers have a CPU to process all the info coming in – Humans have a brain to process everything and to make logical sense of it.

-Computers have RAM to store short-term info and a hard drive to store long term memory – Human brains have the ability to store short and long time memories.

-Computers have output devices like monitors and printers – Humans have output “devices” like hands (we can build/create things) and mouths to talk/communicate with.

-Computers have a motherboard which connects all these components together and make them work together perfectly – Humans have a nervous system which also connects all our “components” together.

-Computers also need software to tell the above hardware components how to work together and how processes must be handled. You get operating system software like Windows and you also get software applications which are software programs that perform specific tasks e.g. MSword is a word processor which you use to type articles like this one – Humans have “software” as well. Our beliefs, habits, emotions, desires and personality are our “software applications” and our “operating system” I believe, is in our subconscious mind. Our subconscious mind runs all the bodily functions 24/7 e.g. breathing, heart rate, cell rejuvenation etc.

Our bodies and brains are nothing short of amazing! We know that computers can be programmed to do certain things in certain ways but can we also program our brains/minds? The answer is yes. If you want to “load” a new program into your subconscious like a new belief or better habit, you can by using self-hypnosis, visualization techniques and affirmations. If you constantly practice this and keep “planting the seed” in your subconscious mind it will soon become real. Psychologists use this technique to help patients overcome mental obstacles. By acknowledging and dealing with the problems then “planting new seeds” in the person’s mind it will “load” the new “program”. This is not brainwashing. Its overcoming old painful/destructive memories that hold you back in life and once you can replace them with more positive “programs” you can see positive results.

We are very similar to computers and we too, can be programmed for better performance!
